Abstract：
Assessing dietary habits with validated questionnaires is crucial for achieving reliable results in health research. The aim of this study was the development and validation of a semi-quantitative food frequency questionnaire (FFQ) in an 18-30-year-old Serbian population. A total of 93 participants completed the FFQ and three 24 h dietary recalls (24 hR). Pearson and intraclass correlations between FFQ and 24 hR intakes were assessed and were de-attenuated and energy-adjusted. Bland-Altman plots were generated, and quintiles of energy, water, fiber, and macronutrient intake were analyzed with contingency tables. Adjustments for sex differences were included. The validity of the FFQ varied, with significant correlations for energy, carbohydrates, cholesterol, and vitamin B12, vitamin C and vitamin D. Misclassification rates were generally low. Bland-Altman plots indicated good agreement between methods. It can be concluded that the validated FFQ is a promising tool for dietary assessment in the Serbian population. Results for several nutrients align closely with previous studies. The new FFQ is a useful tool for dietary assessment in the Serbian population.
摘要：
使用经过验证的问卷评估饮食习惯对于在健康研究中获得可靠的结果至关重要。这项研究的目的是在18-30岁的塞尔维亚人口中开发和验证半定量食物频率问卷（FFQ）。共有93名参与者完成了FFQ和3次24小时饮食回顾(24小时)。评估了FFQ和24hR摄入量之间的Pearson和组内相关性，并进行了减毒和能量调整。产生了Bland-Altman地块，和五分之一的能量，水,纤维,和大量营养素摄入量用列联表进行分析。包括对性别差异的调整。FFQ的有效性各不相同，与能量有显著的相关性，碳水化合物,胆固醇,维生素B12、维生素C和维生素D的误分类率普遍较低。Bland-Altman地块表明方法之间具有良好的一致性。可以得出结论，经过验证的FFQ是塞尔维亚人群饮食评估的有希望的工具。几种营养素的结果与以前的研究非常吻合。新的FFQ是塞尔维亚人群饮食评估的有用工具。
